A PNR (Passenger Name Record) code is the six-character booking reference an airline assigns to your reservation, made up of letters and numbers such as A7F9KQ. You can find it on your booking confirmation email, your boarding pass or e-ticket, and in the “Manage my booking” section of the airline’s website or app.
Your Passenger Name Record (PNR) code may not look like much at first glance. It’s just a short combination of letters and numbers, but it is one of the most important details tied to your flight. Your PNR code works as the key to your booking and allows you to check in, access your itinerary, manage your flight, and, most importantly, support a compensation or refund claim if your journey doesn’t go as planned.
Whether you are flying within the UK, heading to Europe, or travelling to Asia, understanding how your PNR works, and why it matters, can save you time, stress, and money.
Fortunately, you can find your PNR code in a few places.
And if you cannot find your PNR at all, don’t worry. Airlines can usually find it for you with your full name, flight number, and travel dates.

The six-character code is just the label. Behind it, your Passenger Name Record stores the full picture of your trip in the airline’s reservation system. A typical PNR holds:
Because a PNR ties all of this together, anyone who has the code and your surname can usually view or change the booking, which is why you should keep it private.
These terms get mixed up constantly, but they do different jobs. Your PNR and your booking reference are the same thing. Your ticket number and flight number are not.
| Detail | What it is | Format | What you use it for |
|---|---|---|---|
| PNR / booking reference (also called reservation code or record locator) | The ID of your whole booking in the airline’s system | Six characters, letters and numbers (e.g. A7F9KQ) | Check in, manage the booking, contact support, and support a compensation claim |
| Ticket (e-ticket) number | Proof that your ticket has been paid for and issued | 13 digits; the first three identify the airline (its IATA code, e.g. 016 United, 220 Lufthansa) | Refunds, involuntary rerouting, and proof of purchase |
| Flight number | Identifies one specific flight, shared by everyone on board | Airline code plus 1 to 4 digits (e.g. BA117) | Tracking the flight and finding gate, terminal, and status |
The short version: one booking has one PNR, but each passenger on it gets their own ticket number, and every flight on the itinerary has its own flight number.
Once online check-in opens, usually 24 to 48 hours before departure, your PNR allows you to check-in via the airline’s website or app. Just enter the code, confirm your details, and download your boarding pass.
This applies across UK and European airlines such as:
It also helps you avoid queues at the airport. Use it to select seats, update your contact details, or add extras to your flight before departure.
If you need to contact the airline for any reason, having your PNR code ready makes a big difference. Whether you are dealing with a flight delay, a schedule change, or a missed connection, sharing your PNR allows the airline to instantly pull up your booking and assist you more efficiently.
For example, if your British Airways flight from Heathrow is delayed and you contact customer support, your PNR lets them see your entire itinerary and explain your options more easily.
Forgot your gate, terminal, or connection time? Your PNR gives you full access to your itinerary at any time. Enter it on the airline’s website or app to see flight numbers, departure times, terminals, and connection details.
Many airline apps also allow you to link your booking using the PNR to receive real-time updates, such as gate changes or delays, which can be invaluable on busy travel days.
From adding checked baggage and choosing seats to requesting special meals or assistance, your PNR allows you to manage and customise your booking. Airlines also use it to send personalised updates if your flight is disrupted.
If your flight is cancelled or delayed, you’ll usually get rebooking offers, refunds, or alternative travel options through the contact details linked to your PNR, and you may also be eligible for flight delay compensation or cancelled flight compensation.
Airlines make mistakes, and minor name errors are common. So, if you need to correct a spelling mistake on your ticket, you’ll need your PNR. Also, for many short-haul or domestic flights, airlines allow small corrections without much hassle.
For international travel, your booking name must match your passport exactly. Airlines may allow minor corrections using your PNR, but full name changes often require documentation and may involve a fee. Always check the airline’s policy before making changes.

On international flights, you may have more than one PNR, especially if your trip involves a codeshare flight.
For example, if you book with British Airways but part of the journey is operated by American Airlines or Iberia, each airline may issue its own PNR. So, keeping both codes is essential, especially when you check in or contact support abroad.
Different airlines also use different reservation systems. European carriers commonly use Amadeus, while others use Sabre or Travelport (Galileo). This can affect how your PNR appears, but its function remains the same.
There is a second reason you might see more than one code. When you book through a travel agent or a platform like Expedia or Opodo, a copy of your reservation often sits in a Global Distribution System (Amadeus, Sabre, or Travelport) as well as in the airline’s own system, and the two can have different record locators. If the reference on your agent’s confirmation does not work on the airline’s website, use the code the airline itself sent you, or retrieve the booking with your name and flight details.
On international routes, your PNR is linked to your passport details. Airlines and border authorities may use this information for pre-screening, which is why accuracy is critical.
Your PNR is essential if your flight is delayed, cancelled, or overbooked, and you want to file a compensation claim. Here’s how it works.
Whether you submit a claim directly to the airline or use a service such as AirAdvisor, your PNR allows the airline to quickly identify your booking and verify what happened. This reduces delays and back-and-forth communication.
If your flight departed from the UK, arrived in the UK on a UK or EU airline, or departed from the EU, you may be protected under UK261 or EU261 regulations.
Under these rules, you may be entitled to compensation of up to £520 if your flight was delayed by more than 3 hours, cancelled at short notice, or if you were denied boarding. The exact amount depends on the flight distance and circumstances.
Your PNR is a key piece of evidence for claims. It confirms your booking details, flight number, and travel date, which are all required to assess eligibility and submit a successful case.
If your flight was delayed, cancelled, or overbooked within the last three years, you may still be able to claim compensation. Check to see if your flight is eligible.
PNRs can look different depending on the airline, but they all serve the same purpose. Here’s a few PNR codes from some of the most popular airlines.
Regardless of the format, your PNR always links directly to your booking.
Your PNR contains sensitive travel information, so avoid posting your boarding passes on social media because they often include your booking reference and barcode. Treat your PNR like personal data and keep it private to prevent unauthorised access to your booking.
Yes. “PNR”, “booking reference”, “reservation code”, and “booking code” all refer to the same thing: the short code that identifies your reservation.
Most PNRs are six characters made up of letters and numbers, such as A7F9KQ. A few systems use shorter or slightly different formats, but six alphanumeric characters is the standard.
Yes. When you book several passengers in one reservation, everyone usually shares a single PNR, while each traveller still has their own individual ticket number.
No. Anyone with your PNR and surname can often view or change your booking, so keep it private and avoid posting boarding passes online.
You cannot read anything from the characters themselves. A PNR is generated to be unique within the reservation system, so it does not spell out your name, route, or date. To see those details, enter the code in the airline’s “Manage my booking” tool.
Your PNR is printed on your confirmation email, e-ticket, and boarding pass, so start there. If you have lost all three, the airline can retrieve your booking using your full name, flight number, and travel date. Third-party sites cannot reliably look up another airline’s PNR for you.
Your PNR code might look small and easy to ignore, but it quietly does a lot of the heavy lifting when you travel. It is what links you to your booking, whether you are checking in, choosing a seat, dealing with a delay, or trying to sort things out after a disruption.
For UK travellers, it becomes even more important when something goes wrong. Your PNR is often the starting point for enforcing your rights under UK261. Keeping it somewhere safe and easy to access can save you time, lower the stress, and make it much easier to get the refund or compensation you may be owed.
